Information about the new official seals of authenticity

Thank you for your continued patronage of our products.


For products manufactured overseas, official seals will be applied to some of our brands starting August 1, 2024 (Thursday), to certify that the products have been inspected and shipped by our Quality Assurance Department, and to prevent counterfeiting.

The quality assurance department adjusts and sets up each unit to our inspection standards before shipping.

【Afected Products】

  • Bacchus Japan Tune-up Series
  • Bacchus Global Series
  • Bacchus Universe Series
  • Headway Japan Tune-up Series
  • SeventySeven Japan Tune-up Series
Each unit will have a seal applied as proof of inspection completion.

Points of Caution

・Please be careful not to peel it off accidentally when handling. Please note that we cannot reapply the adhesive if it was to come off.

Please be careful not to peel it off as it will look like the picture above if it is peeled off.


・Instruments currently in stock in stores or in the possession of users that were shipped before August 1, 2024, won’t be retroactively provided with a seal.
・Official seals won’t be provided or sold individually.


With the introduction of the Official Seal, we will strive to provide even better products and services in the future by proving that our products have been inspected and shipped by our company and by preventing unauthorized products.
